For the last two weeks our classroom has been working on light thinking keys. There are twenty activities and I was able to complete all 20. My favorite activity was the picture. It looked like this. Here is what I made out of it. The hardest key was the commonality. Which is find common points between sunglasses and a drink bottle. I got some answers eventually. What I learnt was not every thing you think looks easy isn't as easy as you think. I also really liked the invention to finding a toilet in the dark.
